Endress+Hauser”s Levelflex FMP55 multiparameter level transmitter can measure both the overall level of a liquid and the interface between two liquids. The transmitter utilizes two level technologies built into one probe. The transmitter will automatically switch between the technologies in order to provide a concise and reliable interface measurement, even in the presence of emulsion or rag layers. Capacitance is not affected by emulsion or rag layers in interface applications, and the radar allows the transmitter to monitor the overall level as well as the interface level. The transmitter has a multi-echo tracking algorithm that can track up to 20 tank echoes simultaneously as the tank level rises or lowers. This ensures that the transmitter will not make a “jump” to an echo that is not the true level, such as an internal tank obstruction or heater coils. The level sensor has a measuring range of up to 33 ft (10 m). The transmitter offers a 4-20mA with HART output signal plus an optional second 4-20 mA output. With its coated multiparameter probe, the transmitter is a good fit for interface measurement in the oil, gas and chemical industries. It can be used in process temperatures from -58 F to 392 F (-50 C to 200 C) and in pressures from -14.5 PSI to 580 PSI (-1 to 40 Bar). The FMP55 carries an SIL-2 rating, as certified by TÜV per IEC 61508 and has ATEX, IEC Ex, FM and CSA area classification approvals available.
